BOILER.

Application led February 13, 1919. Serial No. 276,800. v

To all 'whom t hwg/concern.'

Be it known that I, RUSSELL R. WATER- MAN, a citizen of the United States, residing at Uplands, in the county of San Bernardino and State of California, have invented certain new and useful Improvements in Boilers, of 'which the following is a specification.

My invention relates to a boiler' for producing a motive fluid for steam engines and the objects of my invention are first, to provide a boiler in which the water is reduced to steam by means of heat produced by the exhaust gases of an internal combustion engine, second, to provide a device of this class in which the motive fiuid produced is a combination of steam and exhaust gases from an internal combustion engine, third, to provide a device of this class in which the lwater is heated by-- induction through the walls of the cylinder of an internal combustion engine; fourth, to provide means for utilizing the heat from exhaust gases for producing steam for use as a motive fluid in a steam engine; fifth, to provide a new and novelly constructed boiler for converting water into steam; sixth, to provide a new and novel method of converting water into steam or vapor for motive fluid purposes and seventh, to provide an apparatus of this class which is simple and economical of construction, durable, very efiicient in its action, easy to operate, easy to install, and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter my invention consists of certain novel features of construe# tion, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set yforth in the appended claims, reference being had to the accompanying drawings an-d to the characters of reference thereon which form a part of this application in which:

Figure l is a sectional view of my boiler complete showing a cylinder andpiston only of the gas engine and showing some of the parts in elevation to facilitate the illustration, Fig. 2 is a top view thereof, Fig. 3 is a sectional View through 3-.3 of Fig. l showing some of the 'parts in elevation, and Fig. 4 is a sectional view through 4 4: of Fig. 1.

l"L of which is adapted to fit -in the compressionchamber 3 and thepart 1 is adapted to fit in the explosion chamber 2 and each portion of the piston is provided with expansion rings lb adapted to provide a tight flt between said piston and the walls of the chambers 2 and 3. Communicating with the lower portion of the explosion chamber 2 are a plurality of inlet ports 2a which communicate with an annular channel 2b extending around said chamber and in communication with this channel 2b are the fuel intake oonductors 2. Mounted in the upper portion of the explosion chamber 2 are the spark plugs 2d which provide for the ignition of the gases in the explosion chamber 2. rlhe compression chamber 3is provided With a downwardly projecting portion 3a and in this downwardly projecting portion is provided a plurality of ports 3b through which the eX- ploded gases pass into the compression chamber '3 and said gases are compressed therein by the inward movement of the piston portion la in said compression chamber 3. This compression chamber 3 communicates with the superheater 6 through a valve 5 which valve is actuated by the pres sure in the compression chamber 3. The outer walls of the compression chamber 3 are provided with a plurality of thin projections adapted to facilitate the induction of heatv from said compression chamber outwardly. Surrounding the explosion chamber 2 and compression chamber 3 is a water receptacle or boiler 4 which is provided with an air space 4 around its outer side for holding the heat this being the preferred construction, however, it is obvious that other insulation may be used if desired. This water receptacle or boiler 4 is provided on its upper end with a head 7 which is provided with an outlet orifice?a therein into which extends the upper end of the super heater 6 which is provided with a plurality of fins 7b for theL purpose of facilitating the induction 0f heat into the steam rising from the water in the receptacle 4. The steam and compressed exhaust gases unite at the end of the super-heater 6 and may be conducted to an engine for use. It will be noted that a plurality of chambers 2 and 3 llke the ones shown and described may be used in one boiler; that the structure herein only discloses one of the several different structures that may be utilized for producing a com-4 bined steam and exhaust gas under pressure for fuel for expansion engines.

It is obvious that with this construction there is provided a means whereby the exhaust gases from an internal combustion engine may be utilized for heating water and producing steam and that the steam may be used for power for steam engines, or that steam may be mixed with the exhaust gases under pressure and the combined steam and exhaust gases used as a fuel for steam or other expansion engines.

The operation of my boiler as disclosed 1s as follows: The fuel enters the cyliner 2 by means of the inlet 2c when the piston is in its receded position, as shown in Fig. 1 of the drawings. At the same time the burnt gases pass into the chamber 3, and with the inward stroke of the piston the exhaust gas is compressed in the chamber 3 and is forced out through the valve 5 into the conductor 6, then passes into the conductor 7. The fresh gas drawn in through the intake 2c is compressed and ignited when the piston reaches the to of its stroke, the piston 1a receding until 1t reaches the lower end of the stroke when the exhaust gases pass into the chamber 3 and fresh gas passes into the cylinder 2. The passage of the burnt gases from the cylinder 2 into the chamber 3 is cut oi by the upward movement of the piston la. Thus it will be noted that the operation of the piston 1 in the cylinder 2 is simi-l lar to that of the ordinary two cycle gas engine. rlfhe heat caused by the explosion of the gases in the cylinder 2 and the heat from the exhaust gases in the chalnber 3 is conducted through the walls of said cylinder and chamber and heats the Water contiguous thereto, transforming it into steam, which passes out through the conductor 7 and intermingles with the exhaust gases. It will be noted that the Water is heated by the cylinder 2 and chamber 3 through the walls .and ins in connection with the chamber 3 and that the steam is super-heated in its passage from the receptacle 4 by means of the exhaust gases in the conductor 6 facilitated by the tins 7".
